Abstract

Issues related to the occurrence of landslides and flooding is a constant in urban daily life, particularly in the rainy season where the problems become evident. These events, in recent years, were not restricted only to large cities but also small towns, which suffer from lack of resources and specialized staff to anticipate and predict resulting tragedies of the floods and landslides caused by the disorderly occupation, especially in Permanent Preservation areas. Over the past 10 years, Santos Dumont has been constantly increasing the number of cases of landslides and especially flooding for not having an integrated planning and active in the containment of such events. The aim of this study is to contribute to the formulation of public policies in order to correct and prevent such events in the urban area of the city. For it was generated a historical data base for a period of 30 years, associated with the processing of images obtained by radar and satellites, provided identify the points that deserve more attention and also made possible through quantitative criterion, propose a hierarchy of neighborhoods that deserve priority in investments related to risk containment. With the combination of maps and the comparison between the study for the preparation of the Master Plan and the historical survey from primary data, it can be observed that most of the cases of flooding and some landslides occur in the course of APP range water. You can also establish a relationship between the neighborhood size and the number of related events to landslides.
